TOBACCO-SMOKING PIPE.

SPECIFICATION forming part of Letters Patent No. 723,672, dated March 24, 1903.

Application filed February 1, 1901. Serial No.45,649. (No model.)

To al whom, it may concern:

Be it known thatI, FRANK HOLLAND, a citizen of the United States, residing at Porterville, in the county of Tulare and. State of California, have invented a new and useful 'Iobacco-Smoking Pipe, of which the following is a specification.

My invention relates to tobacco-pipes; and the primary object thereof is to produce a new and improved device of this character having the heel of the bowl thereof provided with an absorbent material exposed to atmospheric action,whereby the tar accumulating thereon may be evaporated to keepthe pipe-bowl free of all foreign matter.

A further object of the invention is to provide a pipe-bowl of a new ari'd improved con:

struction to obviate any liability of foreign matter, such as ashes or tar, entering the mouthpiece. 1

Still further objects of the invention will appear as the nature of the same is more fully understood from the following description, taken in connection with the accompanying drawings, forming a part of this specification.

In the drawings illustrating the preferred form of my invention, Figure l is a vertical sectional view of a pipe-bowl constructed in accordance with my invention. Fig. 2 is a detail plan View of the absorbent material.

A designates a pipe-bowl open at both ends and of the usual size and configuration, the

same comprising cylinders D, E, and F. The cylinder D is composed of paper, wood, or other suitable material and constitutes the outer surface of the bowl. The cylinder F is composed of asbestos or other equivalent material and forms the inner surface of the bowl, obviating all liability of the interior of the bowl being injured by. fire. The cylinder E is composed of wood or other equivalent passage with the aperture J. The plug hasbowl A.

sition of the absorbent material to atmosthe lower end thereof provided with a recess (3 of a diameter greater than that of the passage B. The recess 0 is adapted to receive an absorbent material to take up all the tar which may accumulate in the passage B, and owing to the fact that the outer surface of the absorbent material is exposed to atmospheric action the tar accumulated by the same will be readily and 'quickly evaporated.

G designates a disk of asbestos adapted to rest upon the plug H to retain the tobacco within the bowl against casual entrance to the passage 8. The disk is provided with a central aperture or apertures of a diameter sufficient to permit of the entrance of the smoke into the passage 3- and then through the aperture to the stem, but not to permit of the entrance of tobacco therein. The absorbent material comprises a plug of two or more layers of felt or any other suitable material and is adapted to occupy the recess 0. The position of the plug I within the recess 0 places the upper surface thereof in position to accumulate all foreign matter entering the passage B and places the lower orouter portion thereof in position to be exposed at all times to atmospheric action, whereby all moisture accumulated bythe plug will be evaporated, keeping the smoke free from obnoxious fluids and poisonous gases and also greatly obviating the necessity of frequently replenishing the absorbent material, the layers of which may be easily removed and replaced by fresh ones. The recess 0 being of a diameter greater than that of the passage B forms a shoulder, against which the plug I is securely pressed and in which position the plug closes the heel of the It will be perceived that the expopheric action will evaporate the tar accumulated by the absorbent material, and thereby render the pipe-bowl free of all foreign substances. v v

It is obvious from the above description, taken in connection with the accompanying drawings, that I provide a pipe-bowl and absorbent of a new and improved character and also that the pipe is cheap, durable, and efficient. It may be further stated that as the stem does not project into the passage B all liability of foreign matter accumulated in a stem-receiving opening, a plug in the base of the bowl formed with vertical and horizontal passages and a recess, and a pad of absorbent material arranged in the recess with its lower end exposed to the atmosphere.

4. A pipe comprising a bowl constructed of cylinders of asbestos, wood, and paper, and provided with a stem-receiving aperture, a

plug mounted in the bowl and provided with a vertical passage, and a horizontal passage in alinement with the aperture, said plug being provided with a recess, an asbestos disk mounted in the bowl and resting upon the plug, and an absorbent material secured in the recess, and having a portion thereof exposed to atmospheric action.

5. A pipe com prisinga bowl, means for supporting the tobacco within the bowl, and a pad of absorbent material arranged in the base of the bowl with its lower end exposed to the atmosphere.

6. A pipe comprising a bowl, and a pad of absorbent material formed of removable layers, and arranged in the base of the bowl with its, lower end exposed to the atmosphere.

FRANK HOLLAND.
